Endometriosis's pathophysiology remains incompletely understood, with evidence pointing towards a dysregulated immune response. Regulatory T (Treg) cells, pivotal in maintaining self-tolerance, may facilitate the survival of ectopic endometrial cells within the abdominal cavity, thereby contributing to endometriosis development. This study aimed to assess the prevalence of CD39+CD73+ suppressor Treg cell subsets in the peripheral blood of endometriosis patients.

Adenomyosis is associated with dysmenorrhea and chronic pelvic pain; however, the triggering mechanisms of painful stimuli and the role of uterine nerve fibers in the manifestation of pain remain poorly understood. The objective of this study was to systematically review the role of uterine nerve fibers' presence and density in the occurrence of pain in patients with adenomyosis. An electronic search was performed using the Embase, PubMed/Medline, and Cochrane databases.

Establishing objective criteria to assess endometriosis symptoms is crucial in defining therapeutic strategies. The visual analogue scale (VAS) is the most used system to enhance the accuracy and reduce the subjectivity of pain assessment, and symptoms of endometriosis are considered severe when the VAS score is ≥ 7 cm. Pain symptoms can significantly impact patients' quality of life, resulting in psychological and social distress.

Article Synopsis
  • Endometriosis is categorized into three types: superficial, ovarian, and deep, with deep endometriosis (DE) often leading to more severe pain symptoms.
  • A study involving 1116 women showed that severe symptoms like dysmenorrhea (painful menstruation) and dyschezia (painful bowel movements) are linked to DE, especially in the posterior compartment of the pelvis.
  • The research also found a connection between infertility and DE, with the most significant effects seen when both posterior and anterior compartments are involved, highlighting the complexity and impact of DE on women's health.

Objective: To evaluate the expression of Ezrin and Phosphorylated Ezrin (Phospho-Ezrin) in endometriosis lesions and its relation to the menstrual cycle phase, stage of endometriosis, histological classification, and clinical symptoms.

Material And Methods: The authors conducted a retrospective study, with endometriotic lesions collected from women with endometriosis (n = 57) who underwent laparoscopy from 2017 to 2018. The expression of Ezrin and Phosphorylated Ezrin proteins was analyzed by immunohistochemistry.

Objective: To evaluate the frequencies of iNKT cells and their subsets in patients with deep endometriosis.

Methods: A case-control study was conducted between 2013 and 2015, with 73 patients distributed into two groups: 47 women with a histological diagnosis of endometriosis and 26 controls. Peripheral blood, endometriosis lesions, and healthy peritoneal samples were collected on the day of surgery to determine the frequencies of iNKT cells and subtypes via flow cytometry analysis.

Introduction: Endometriosis is a chronic inflammatory disease that affects approximately 10%-15% of women of childbearing age. Laparoscopic surgery is the preferred surgical approach. Recently, robotic surgery has been used for benign gynecologic surgery, but its role in the treatment of endometriosis is still unknown.

Endometriosis (EDT), a common estrogen-dependent inflammatory disorder, is characterized by endometrial-like tissue outside the uterus. While its pathogenesis is poorly understood, it is supposed that the immune system plays a role in its pathophysiology, and increased number of immune cells and changes in both cell-mediated and humoral immunity have been described. Dendritic cells (DCs) are antigen-presenting cells (APC) of the immune system that recognize, capture, and process complex antigens and present them to T cells, conferring them a unique ability as mediators between the innate and adaptive immune systems.

Objective: To evaluate the association of two-dimensional (2D) and three-dimensional (3D) transvaginal ultrasound (TVUS) findings with adenomyosis symptoms.

Methods: This prospective study conducted between January and December 2018 enrolled 78 women aged 18 to 40 years with abnormal uterine bleeding (AUB), infertility, and/or pelvic pain. All patients underwent 2D and 3D TVUS.

Purpose Of Review: Laparoscopic myomectomy is a common surgical procedure for symptomatic myomas. However, bleeding control during surgery may pose a challenge. Therefore, the aim of this study was to review recent evidence regarding interventions to control bleeding during laparoscopic myomectomy.

Study Question: What is the sensitivity and the specificity of preoperative transvaginal ultrasound with bowel preparation (TVUS-BP) compared to diagnostic laparoscopy (DL) for the identification of ovarian and deep sites of endometriosis?

Summary Answer: DL was able to detect retrocervical, ovarian, and bladder endometriosis with similar sensitivity and specificity as TVUS-BP, whereas for vaginal and rectosigmoid endometriosis, DL had lower sensitivity and specificity than TVUS-BP.

What Is Known Already: TVUS-BP is a non-invasive examination with good accuracy for diagnosing ovarian and deep endometriosis. DL is expensive and can lead to surgical complications.

Purpose: MRI plays an important role in the diagnosis and surgical planning of pelvic endometriosis (PE), and imaging reports should contain all relevant information (completeness). As structured reports are being increasingly utilized, we aimed to evaluate whether structured MRI reporting increases the quality of reports regarding completeness and, consequently, their perceived value by gynecologists, in comparison to free-text reports. We also aimed to compare the diagnostic performance of both formats.

The aim of this study was to evaluate progression of the bowel endometriosis lesion over time. We performed a retrospective cohort with 164 patients with rectosigmoid endometriosis identified by transvaginal ultrasound (TVUS) with bowel preparation waiting for surgical treatment. Length and circumference of the bowel lesion evaluated by TVUS, painful symptoms (dysmenorrhea, dyspareunia, noncyclic pelvic pain, dyschezia, dysuria), and menopausal status were assessed at baseline and 6, 12, 24, 36, and > 36 months.

Endometriosis is a chronic disease that affects 5-15% of women of the reproductive age. Different classifications systems have been proposed to categorize endometriosis. In 1979, the American Fertility Society proposed a new system for the classification of endometriosis to correlate surgical findings of endometriosis with fertility, and this system was revised in 1996 (rASRM).

Treatment options for patients with different types of endometriosis - superficial, ovarian, or deep - vary depending on the clinical presentation. New findings in the recent years regarding the role of preoperative imaging, efficacy of medical therapy, and effect of surgery on ovarian reserve have changed the way we understand the disease and subsequently the way we treat our patients. Practicing clinicians frequently refer to published recommendations from major societies for treatment guidelines.

Adenomyosis is a benign gynecological disease observed in women in their reproductive age. Recent studies have shown that adenomyosis might be a relevant factor for infertility, either impairing implantation or leading to early miscarriage. However, conservative treatment of infertility related to adenomyosis is still unclear.
